We sort of love the idea of the Palatov DP4, which is a track-toy kit car that combines the best aspects of a go kart with the closed-wheel design of a Batmobile. The DP4 is really like getting two in-one.

The dp1/e is a purpose-built electric racer. It weighs just 1,100 pounds and turned a 1:53 lap around Laguna Seca during this year's REFUEL electric car race, ahead of every Tesla there. [dpCars via TractionInc]
